ATTORNEYS PATENTED M1822 m2 SHEET 3 GE 3 INVENTOR GEOFFREY GEORGE WGRTHINGTGN 7 7 VICES This invention relates to a vice and an assembly for a,

vice part.

The two vice jaws of a workbench vice are usually formed integrally with the body and slide respectively,

the slide being the part movable relative to the body so that when an article to be worked upon is placed between the jaws and the slide is moved towards the body, the article can be gripped between the vice jaws. Although satisfactory for gripping most articles, conventional vices are not suitable for gripping a tapering article because only a small proportion of the surface area of the vice jaws contact the article. Apart from the possibility that the vice jaws may damage a tapering article, there is also the chance that the article may not be firmly secured between the vice jaws and may move while it is being worked upon.

The invention consists in a vice comprising a body part, a slide part movable relative to the body part and a jaw member adapted to be mounted on the body part and/or the slide part, the arrangement being such that the jaw member can move angularly in a plane.

The invention also consists in a vice comprising a first part, a second part movable relative to the first part, a jaw member adapted to be pivotally supported by the first part, an operating means for moving the two parts towards and away from each other.

One of the parts may have a convex surface and the jaw member has a corresponding concave surface so that the jaw member can pivot about the convex surface.

One of the parts may have a recess and the jaw member has a projection adapted to enter the recess when the jaw is mounted on the said one part, a portion of the jaw member and a portion of said one part being arranged to leave a gap therebetween or one of the said portions being deformable so as to enable the jaw member to pivot relative to the said one part.

There may be a second jaw member adapted to be pivotally mounted to the second part.

The invention also includes an assembly for a vice include an adaptor member adapted to fit onto a portion of a standard vice and a jaw member adapted to be pivotally supported by the adapter member.

Examples will now be described.

In the accompanying drawings:

FIG. 1 is a side view of a vice showing two examples of the invention with the left hand jaw in its fixed position.

FIG. 2 is a plan view.

FIG. 3 is a section in the direction of arrow III of FIG. 1 without the left hand member.

FIG. 4 is a rear view of the left hand jaw member.

FIG. 5 is a section on the line VV of FIG. 4.

FIG. 6 is a sectional view in the direction of arrow VI of FIG. 1 without the right hand jaw member.

FIG. 7 is a rear view of the right hand jaw member.

FIG. 8 is a section along the line VIII-VIII of FIG. 7.

FIG. 9 is a scrap side view showing the left hand jaw member in its furthest downwardly adjusted position.

FIG. 10 is a sectional plan view of a part of the vice of FIG. 1 showing the right hand jaw in adjusted positron.

FIG. 11 shows a mount for adding to existing vice to simulate left hand side of the vice of FIG. 1.

FIG. 12 shows a mount for adding to existing vice to simulate right hand side of the vice of FIG. I.

In FIG. 1 there is a body 1 having a face 2 onto which a first example of the jaw member, namely jaw 3. A

slide 4 is axially movable in body 1 and has a face 5 onto which a second example of the jaw member, namely jaw 6 can be fitted. The face 2 has a convex portion 7, an upper ridge 8 which extends across the lateral width of the face 5 and a lower ridge 9 which has a central projecting portion '10. The jaw member 3 has a main body portion 11 having a concave surface to fit convex portion 7, an upper rearwardly extending rim 12, a lower rearwardly extending rim l3 and two end portions 14 and 15 having two slots l6and l7 respec tively. The body portion 11 has a central recess 18 along the central part of its inner upper edge and this recess 18 must be at least as long as portion 10 and terminated at each end by a shoulder 18a.

When jaw member 3 is fitted onto face 2 of body 1, pins 19 extending transversely outward from one side of block 1 and another pin projecting out from the other side of block 1 engage the slots 16 and 17 to locate jaw 3 on block 1. If the jaw 3 is mounted with slot 17 on the pin 19 as shown in FIG. 9, the jaw 3 can pivot about pin 19 as shown, but if the jaw 3 is reversed so that slot 16 is located on pin 19 as shown in FIG. 1, then jaw 3 is not pivotal but fixed.

In FIG. 9, the jaw 3 has been pivoted about pin 19 into its most downwardly position where portion 10 is located in the recess 18 whereas, in FIG. 1, the jaw 3 has been reversed and portion 10 now abuts the edge face 20 (FIG. 4) of jaw 3 which edge face is free of contact in FIG. 9 and defines a cavity 21 with the face 2 of the bodyl. In this manner, jaw 3 pivots in a vertical plane but can be fixed in the normal position.

FIG. 6 shows the face 5 of slide 4 which face has a recess 22, a recess 23 and an open-sided slot 24 of less depth than recess 23 and connecting recess 23 with the side edge of face 5. The jaw 6 has a projection 25, and a projection 26 and an outer projecting rim 27. There is also two champfered recesses 28 which gradually deeper in the transverse direction towards that part of the rim 27.

In FIG. 10 the projections 25 and 26 are located in recesses 22 and 23 respectively, and a wedge-shaped article is held between the jaws 3 and 6 so that jaw 6 has pivoted to its furthest possible pivoted position in the horizontal plane and projection 25 has moved slightly out of recess 22 and champfered recesses 28 abuts the bottom of slot 26. Of course by reversing projections 25 and 26 in slots 22 and 23, jaw 6 is then fixed movable to pivot jaw 8.

In FIGS. 11 and 12 are shown two adapters 30 and 31 adapted to fit onto the jaws of a conventional vice and provide faces 32 and 33 corresponding to faces 2 and 5 of the vice shownin FIG. 1 so that the two jaws 3 and 6 can then be fitted to the adapters 30 and 31 respectively to convert a conventional vice.

In FIG. 1 the slide 4 has a tightening or tommy bar 40 for rotating screw threaded rod 41 to move slide 4 relative to body 1. Body 1 has a bracket 42 carrying a screw threaded clamping member 43 which can clamp to a work bench. This bracket is connected to body 1 by two bolts 44 and it can be arranged to attach this bracket to flanges 45 of body 1 through apertures 46 if desired.

Clearly the projections on jaw 6 and corresponding recesses in face 5 could be spaced from each other vertically rather than horizontally so that jaw 6 would then pivot in a vertical plane. Similarly, pin 19 could rise leaves no gap therebetween. Thus jaw 6 is not horizontally pivotal but jaw 3 is vertically pivotaland will accommodate to the tapered article as slide 4 moves towards body l to clamp the article. If the article is then taken out of the vice and turned through 90 so that it tapers horizontallythen both jaws 3 and 6 are reversed to their other positions on the body 1 and slide 4 respectively, so that shoulder 18a abuts ridge 8 and recess 18 lies along side ridge 8 and face 20, abuts portion so that jaw 3 is immovable whereas raised portion 29 is spaced from open-sided slot 24 to allow jaw 6 to pivot horizontally to accommodate the taper of the article, a slide 4 is moved towards body 1.

It will be appreciated that the champfered recesses 28 could be substituted by deformable, for example, resilient material.

It is possible for the convex surface 2 and pin 19 to be provided on the rear face of the pivotable jaw member 3 and .a corresponding concave surface and slots can be provided on the body 1.

Clearly, it is also possible for the recesses 22 and 23 to be provided on the rear face of the jaw member 6 and the projections 25, 26 to be provided on the slide 4.
